| Summary: | 碩士 === 國立中興大學 === 土木工程學系 === 87 === Hydrogeological data is provided to be the basic decision support for landslide remediation. Geographic information system(GIS) is used for data management and spatial analysis and forms the decision support system query ,display and analysis. Hydrogeology is established by ARCVIEW software and 3D analytic model to form an intact hydrogeological information system.
In Lisun landslide area, discussion of it hydrogeology are divided into three parts. First, drainage analysis of its geography is used to understand situation of drainage in Lisun and discuss completed drainage work. Second, geological layers distributions built using drilling data. Then, the spatial interpolation model developed in this research is provided to predict the system of geological layers. Third, flow direction analysis of groundwater is accomplished using relational theory of hydrology to get its initial flow direction. Then, with the considering geological situation, allover flow direction of groundwater is suggested. 3D modeling and hydrogeological analytic method developed in this research are also provided to discuss drained validity of drainage well. This process can explain that effect of drainage work in Lisun has met problem, and offer the improving direction.
The result of hydrogeological statement in Lisun verified that GIS can be used to analyze and implement for the hydrogeological framework. Functions of GIS , including of display,3D model, and renewal, support hydrogeological analysis can be applied applied to data management and decision support system in landslide area.
